Abstract

The present application discloses a package structure, a display panel and a display device, wherein the package structure includes a first organic layer and a package unit arranged on the first organic layer; On the side, liquid crystal molecules are evenly distributed in the first organic layer, so that the light passing through the first organic layer is converged and emitted within a fixed angle range. By setting the first organic layer on the illuminated side of the packaging structure, The first organic layer has the same refractive index as the material of the light-emitting layer in the OLED display panel, so that there is no refraction interface between the encapsulation structure and the light-emitting layer. After the light passes through the first organic layer, it is converged and emitted within a fixed angle range, thereby improving the light extraction efficiency of the OLED display panel. In addition, the light is dispersed by combining the light-scattering layer to meet the requirements of wide viewing angle and low color shift.

Description

technical field [0001] The present application relates to the technical field of display panels, and in particular to a packaging structure, a display panel and a display device. Background technique [0002] OLED display panels have become the focus of research and development and production due to their wide color gamut, wide viewing angle, high contrast, and flexibility; the existing thin-film packaging structure is mainly carried out in the form of overlapping inorganic film layers / organic film layers. The inorganic film layer mainly plays the role of barrier protection, which is used for water and oxygen barrier; the organic film layer mainly plays the role of slow release stress, particle covering and so on. [0003] At present, the light-emitting layer in OLED display panels is mainly formed by vapor deposition of small molecule organic materials, and the refractive index (RI) of the material is mostly 1.4-1.7. The refractive index of the inorganic film layer of the T...
